Bismuth Telluride

4N N-type Bismuth Telluride
Bismuth telluride is a compound of tellurium and bismuth. It is a narrow-gap layered semiconductor with a triangular unit cell. It is mainly found in the rare mineral bismuth telluride.

4N P-type Bismuth Telluride
Bismuth telluride is a semiconductor material with good conductivity, but poor thermal conductivity. It is mainly used for semiconductors, electronic refrigeration and power generation.
